Recent forecasts from the Korea Meteorological Administration and international models indicate mostly cloudy skies with scattered showers and thunderstorms for the Seoul-Incheon region on August 28, limiting daytime solar heating and supporting a peak near 30°C. Persistent high humidity and southeasterly flow ahead of a frontal system are expected to cap temperatures, aligning with the market's leading 30°C (41.5%) and 29°C (22.5%) outcomes while leaving room for 31°C (18.5%) if convection is delayed. These conditions contrast with recent hotter, drier days and historical late-August averages near 27–28°C, with traders weighting official guidance and ensemble consensus on precipitation timing. Updated model runs and KMA briefings over the next 24 hours will likely refine the exact maximum before resolution.

The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=rksi
If NOAA data is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
